Posted 2 Oct 2016 Please demonstrate that you have read the manuals relating to the PLC and the VFD. Post PDF diagrams of your electrical control wiring. Post a zipped copy of the PLC ladder logic you have developed so far. Note where you arre having problems including steps you have taken to troubleshoot. Until you have done these things do not expect much help (especially since you are a student and this should be a learning experience for you.) Share this post Link to post Share on other sites
Posted 3 Oct 2016 SAHILGUPTA1527...you have posted this same request in 3 different areas of this forum all with the same results...others about ready to support you, but your question is vague and obtuse. Then you add that you are a college student, this is a project, and you are on vacation. I sure hope your professor does not monitor this forum. Share this post Link to post Share on other sites
